expand (x^2+1)/((x+1)(x^2+4))

expand

\frac{x ^{2} + 1}{( x + 1 ) ( x ^{2} + 4 )}

\frac{x ^{2} + 1}{x ^{3} + 4 x + x ^{2} + 4}

Solution steps

\frac{x ^{2} + 1}{( x + 1 ) ( x ^{2} + 4 )}

Expand

(x + 1) (x^{2} + 4) : x^{3} + 4 x + x^{2} + 4

= \frac{x ^{2} + 1}{x ^{3} + 4 x + x ^{2} + 4}

\frac{1}{2} (u^{2} - 4 + u)
